Application led April 11,1910. Serial No. '554,656.-

' Beit known that I, WILLIAM K. HE/NKY; a citizen of theUnited States,residing 'atv `New Britain, county ofHartford', State of Connecticut,have invented certain new anduseful Improvements in Adjustable Door-Stops, of `which the following is a `full, clear,

and exactv description. y

"of a door closer ofthe conventional type fitted with my' improyedadjustable stop, and showing the levenarni in approximately the positionin which it stands when the door 'to whichthe apparatus-is applied isclosed.A Fig. 2 .is a side' elevation of the .same parts,l

lthe arm/being shown as engagedby the stop.

' Fig. 3 is'aiilend elevation of 2, looking fromfl'eft to right. Eig. 4is a longitudinalsectional vview of certain-details. v

Projectl' fing upwardly through thecapl is acentral shaft. 3, upon -Which is mounted a lever 4. VIn this particularinstance, the lever 4 is connected by a dog 5. to a spring. drivensleeve, ofA which sleeve, AG is a-flanged portion. The dog-*f5 takesinto notches of.the.

.-.iange 6 of .thefsleevef and the spring, or equipment means 1 (not.shown) operates to movethelever arm 4 inv one direction.Thissprin,g-impelled movement of' the lever j 4 isin la vdirection toclose' the door, said lever 4 normally standing, when the door isclosed,"`

in `approximately the position lshoigvn in Fig.j1. 1 7 is a strapencircling the cap, said strap bearing thereon avstop lug 8, over whichthe lever arm 4 may swing. The strap 7 is ca. l p l Y Witnesses:

I n the resent instancethelatch member A.10 has la s iding-bearing'in asleeve 12,1 ipon which the dog 5 is mounted.- The spring lat-ch 10l is`preferably provided with an inclined bearing face, and its distance fromthe axial center' of the shaft or spindle 3 is -suchtha't said latchwilll he obliged to ride over the stop.8 when -the lever has been swungsuiiciently far in a direction tdWard saidstop. The stop shouldv beadjusted at such a position that `it will engage the latch 10 when theydoor stands ajar tothe desired degree. The tension of the spring l1 is'-sufficient to overcome the tension of the closer spring when the latch10 Yis-back ofthe stop^-8..

When it is desired to'close the door. from the stopped position, "aslight manual Apressurey against the rear ofythe door is suficient' toovercome the tensioniif the .spring 11, repress'ing the latch 10,whereupon the doormay then close under the action ofthe mechanicalcloser device.

- What I claim is:

a lever arm mounted tol swing concentrically with the axis of thespindle, a stop adjustably mounted upon the lperiphery of the cap'portion of the case at its greatestldiameter andarranged lto be shiftedto diierent posit-ions angffarly around the axis .of said spindle, in:ns tor' holding the stop in Avarious pos. onsv :if adjustment, said-nieans 'comprising a split strap and al clamping screw for securing theends o f saidjsplit strap.v a coperating stop engaging member arried-'bythe lever arm, one of said stoplOO elements being spring pressed and.yielding.
